Are there any Minecraft command generators that can make a Sword of the Sun with the same enchantments?
/give <Player> minecraft:diamond_sword 1 0 {display:{Name:"Sword of the Sun"},ench:[{id:16,lvl:5},{id:20,lvl:10000},{id:21,lvl:10000},{id:34,lvl:10000}]}
Copy this in one command block for a diamond sword that is unbreakable has Sharpness V, Fire Aspect, and Looting 10000, and is named 'sword of the sun'. Now for the effect of fire invulnerability...
Place a command block next to that one and type in or copy and paste...
/effect @p fire_resistance 1000000 300 true
Link them together with redstone and activate. If this doesn't work then let me know, it would probably be because of the new update some commands work differently now.
